Frequently asked questions (FAQ)
How much smaller will my file get?
It depends on the content. Scanned documents and files full of photos shrink the most, often by more than half.
Will I lose text quality?
Light keeps text as it is. Recommended and Extreme turn pages into compressed images, so text stays readable but can no longer be selected.
Why did you say my file can’t be made smaller?
Some PDFs are already fully optimized. In that case a new file would be larger, so we do not return it.
Are my files uploaded?
No. Compression runs locally in your browser.
Conclusion
Smaller files mean faster sharing. Try the Free Online PDF Compressor on your next large document.
